Cat scratches base corner of cat tree — fix it

So you've got an expensive cat tree and she's ignoring all of it except one corner of the base — that's actually a really telling sign. The most common reason cats do this is the post sections on the tree aren't tall enough or stable enough for a proper stretch, so they find the one spot that doesn't move. Before I point you toward something better, a couple of quick questions: how big is your tortoiseshell — is she a stocky build or lean? And is that base corner sisal, carpet, or cardboard?

That tells you everything — she's given you a very clear vote for sisal over carpet, and she's scratching low because nothing tall enough is giving her the stability she wants when she pulls down into a stretch. Carpet posts tend to snag claws rather than letting them drag cleanly, which most cats dislike. For a lean, medium cat she'll want a post of at least 90cm to get a full vertical stretch. How does she scratch — does she go fully upright, front paws high, or does she tend to scratch more at an angle close to the ground?

Perfect — that confirms she wants a tall, vertical sisal post with a base that doesn't shift at all when she leans into it. My recommendation is the Vesper V-Tower. It's 110cm tall, fully wrapped in natural sisal rather than carpet, and the weighted base is genuinely solid — it won't rock when she pushes against it. A lot of cats who scratch the base of trees switch to it immediately because it finally gives them what they were looking for in the first place. It also has a top platform, which is a bonus for a cat who already likes elevated spots. I'd skip anything under 100cm for a cat who stretches that high.

Location matters more than most people realise. Put it somewhere she already spends time — near where she sleeps or in a room where the family sits. Cats scratch partly to mark territory visually and with scent, so they want the post somewhere that feels significant to them, not tucked in a corner of a spare room. If you can, place it near the cat tree initially so she makes the connection. Once she's using it regularly you can gradually move it if you need to. Don't bother with catnip spray — with sisal and the right height, most cats work it out on their own within a few days.

Good choice. Given what she's already been telling you with that base corner, I'd be surprised if she doesn't take to it quickly. If for any reason she's slow to engage, try rubbing a little of the sisal from the base corner onto the new post — transfers the scent and often speeds things up. Hope she approves.
